I had heard about this Looney Tunes quite often and when I realised (when it said on this site) that it was a spoof on Fantasia, I became very excited. I kept thinking, "Ooh, I'm so excited to find out what this is like." When I watched this on YouTube, I was very impressed.
I find this very much a classic Looney Tune - highly entertaining, funny and sweet. The Fantasia spoof around it works very well. I also noticed that there was only one joke which was relevant to the world of the time. It was a slight fighter jet joke and of course the Second World War was still raging in 1943. Some of the jokes were slightly lame and a little repetitive/predictable, but a delight to watch all the same.
Also, this has a role of Daffy - who does not look a lot like Daffy. Daffy looks much more like a duckling than the little black duck we know. He does a very good job. Of course, so does everyone in this episode.
Being a spoof on Fantasia, there are two stories, both with a piece of classical music in the background. Elmer Fudd introduces each piece and has rather a trouble with his out-fit (you'll see what I mean when you watch it). I personally preferred the second piece to the first piece, partly because the second had Daffy in it.
Recommended to people who enjoy old Looney Tunes cartoons and who very much enjoy "Fantasia". Enjoy "A Corny Concerto"! :-)
